I am planing on puting air bags on the back of my truck and need some help designing a system for my 59 chevy that i am making into a rollback so the air ride has to be strong, the air bags that I am using are off of a frieghtliner truck. what size air tank do I need? how big of a compresser? I also plan on running a air hose off of the system. how about valving. does any one have any experties in designing a good system
